CDNBS08-T15C application field and working principle

A Transient Voltage Suppression (TVS) Diode is a type of device used for protecting sensitive electronic equipment from momentary high voltage transients such as lightning strikes and power surges. The CDNBS08-T15C is a high-performance, low-capacitance, bidirectional TVS diode with a 600 W peak pulse power rating. It is designed for use in both industrial automation and consumer/commercial applications.

Features and Benefits

The CDNBS08-T15C has the following features, benefits and characteristics:

• Extremely low capacitance, typically 8.4 pF, which reduces system cost and is beneficial in high-speed, low power applications
• High peak power of 600 W, ensuring that it can handle the most extreme transient voltage spikes
• Bidirectional protection for both positive and negative transients
• High surge current of 12 A maximum
• Low clamping voltage of 32 V maximum
• Contact-less construction makes it suitable for high humidity environments

Working Principle

The CDNBS08-T15C incorporates an N-P-N structure for protection against both positive and negative transients. When a surge voltage greater than the breakdown voltage is applied, a current will flow through the diode and the voltage will be clamped to the breakdown voltage. The CDNBS08-T15C can withstand up to 600 W of peak power and 12 A of surge current for short durations without damage. The low capacitance across the device ensures that it does not affect the signal quality and does not introduce high frequency noise.
